Ngokuphathelene nezinto zepulasitiki, kunezindlela ezahlukahlukene emakethe ongakhetha kuzo. Izinto ngazinye zinezakhiwo zazo ezihlukile kanye nezinhlelo zokusebenza, ngakho-ke kubalulekile ukuqonda umehluko nokukhetha izinto ezifanele izidingo zakho ezithile. Kulesi sihloko sebhulogi, sizoxoxa ngomehluko phakathiIshidi le-PPkanye nebhodi le-PP, izinto ezimbili zepulasitiki ezidumile ezisetshenziswa kabanzi ezimbonini ezahlukahlukene.
Kokubili ishidi le-PP kanye nebhodi le-PP kwenziwe nge-polypropylene, i-polymer ye-thermoplastic enezakhiwo ezinhle kakhulu. Yaziwa ngokumelana kwayo nokukhathala okuguquguqukayo kanye nokumelana nokushisa okuhle kakhulu, i-polypropylene ilungele ukusetshenziswa okudinga ukuqina kanye nokumelana nokushisa okuphezulu.
Umehluko omkhulu phakathi kweshidi le-PP kanyeIbhodi le-PPilele ezimpahleni zazo zomzimba.Ishidi le-PPiyishidi lepulasitiki elincane elinamandla amakhulu okudonseka kanye namandla ongaphezulu. Avame ukusetshenziselwa izinjongo zokupakisha njengoba ehlinzeka ngesivikelo esihle kakhulu futhi amelana nokuguguleka kanye nokushiswa yi-oxidation. Amashidi e-PP ayaziwa nangokumelana kwawo namakhemikhali aphezulu, okwenza afaneleke ukusetshenziswa embonini yamakhemikhali.
Ngakolunye uhlangothi, ibhodi le-PP likhulu futhi linamandla kunephepha le-PP. Ngokuvamile lisetshenziswa ezicelweni ezidinga amandla aphezulu nokuqina, njengezibonakaliso, izibonisi kanye nezingxenye zesakhiwo. Ibhodi le-PP liphinde libe nokumelana nokukhathala okugobile kanye nokumelana okuhle nokushisa, okufana nephepha le-PP.
Nakuba kokubili ishidi le-PP kanyeIbhodi le-PPNjengoba zinezici ezifanayo, kubalulekile ukunaka umehluko ekulinganiselweni kwazo. Ishidi le-PP kulula ukulibopha uma lishisa futhi alinawo ukumelana nesimo sezulu. Ziyinselele futhi kuma-varnish nama-glue, futhi azikwazi ukushintshwa ngesivinini esiphezulu. Ngakolunye uhlangothi, amaphaneli e-PP nawo anale mikhawulo kanye nobunzima ekupendweni nasekubopheni.
Uma ukhetha phakathi kweshidi le-PP nebhodi le-PP, kubalulekile ukucabangela izidingo zakho ezithile kanye nokusetshenziswa okuhlosiwe. Uma udinga into encane futhi eguquguqukayo enokumelana okuhle kwamakhemikhali, ishidi le-PP lizoba yisinqumo esifanele. Ngakolunye uhlangothi, uma udinga into eqinile enamandla nokuqina okuphezulu,Ibhodi le-PPkuzofaneleka kakhulu.
Ngamafuphi, kokubiliIshidi le-PPkanye nebhodi le-PP kuyizinto zepulasitiki ezisetshenziswa kabanzi ezinezakhiwo zazo ezihlukile kanye nezinhlelo zokusebenza. Nakuba zabelana ngezakhiwo ezifanayo, njengokumelana nokukhathala nokushisa, kubalulekile ukucabangela ukulinganiselwa kwazo lapho wenza isinqumo. Ngokuqonda umehluko phakathi kwephepha le-PP nebhodi le-PP, ungenza ukukhetha okunolwazi bese ukhetha izinto ezifanele kakhulu izidingo zakho ezithile.
